Title: Semiconductor integrated circuit
Inventor: MATSUNO SHUNJI
IPC: H03K19/00
Filed: 1985-09-04
Abstract: PURPOSE:To prevent malfunction during the testing of a single integrated circuit, by a method wherein an output buffer circuit is kept at a high impedance while the internal circuit of the integrated circuit is in operation and waiting for the end of the operation, it is put to the normal output state by lagging time in each group to minimize the peak value of current flowing through a buffer section. CONSTITUTION:A disable signal to be applied to an internal terminal 1 gives '1' before a test data is inputted, and so 3-state output buffer circuit 100-400 are all at a high impedance (HZ) when a test data is inputted. There is no variation in the output during the operating of the internal circuit of an integrated circuit after the inputting of the test data and waiting for the end of operation, the circuits 100 alone are put to the normal output state from the HZ state, and then the circuit 200 is put to the normal output state at the timing delayed by a time determined by a resistance R1 and a capacitance C1. Thereafter, likewise, the output is varied by a delay time up to the circuits 400, thereby allowing the circuits to avoid the flowing of a large current there through at one time.

Abstract: PURPOSE:To obtain the nth root with a simple constitution at a high speed by changing the coefficient of a noticed position according to the result of comparison between the nth power value of the approximate value of the nth root and the input numerical data. CONSTITUTION:The n-root C 108 of (k) figures is obtained for input numerical data A 107 of (nXk) figures which is shown in the binary numbers. In such a case, the coefficients are successively decided from the highest position of n-power figure C 108 and therefore the approximate value X 110 of the n-root C 110 is stored in an approximate value register 102. Then the approximate value X 110 is supplied to an nth power arithmetic part 101 and the nth power value B 109. A comparing part 100 compares the value B 109 with the input numerical data 107. While a noticed position designating part 104 designates successively each position (noticed position 111) of an approximate value register 102 from the highest position. Then, a coefficient setting part 103 sets the coefficient of the position 111 at the prescribed value every time the position 111 is designated. A coefficient changing part 105 changes the coefficient of the position 111 to the appropriate value.

Filed: 1985-09-09
Abstract: PURPOSE:To allow a small sized central supervisory device to troubleshoot easily a faulty location of a main line by arranging collected fault information in the prescribed order and retrieving the faulty information in opposite direction to the signal flow. CONSTITUTION:The fault information is rearranged in the order corresponding to the signal flow in the main line 11 in repeater supervisory devices 5-8, and the generated fault information is all preserved until a transfer request comes from a central supervisory device 9. Then the device 9 makes request of the transfer of the fault information in order from the lower stream of the signal from to the supervisory devices 5-8 of terminal station devices 4-1. In such a case, when no fault takes place in each fault information, the device 9 neglects it and when a fault exists, it is stored in a memory as the highest priority fault information. As a result, when the retrieval is finished up to the device 1, the fault information in the memory is the fault information of the uppermost flow on the main line 11 and the fault information is specified as the highest priority fault information.
